This is looking fantastic! Types of References I would use here would be videos of deer, light patterns off of shiny things, and water studies /refraction/ jelly studies (to cheat in shadows to enrich a piece) High high lights and Low low Darks to dramatize the differences

I notice the horns are somewhat super spaced apart- with the furthest horn super forward. The horns may appear closer together from this angle unless the head is somewhat side tilted away from us. When cows are lifting or deer are lifting their head, sometimes the furthest horn disappears or falls closely in line. Nudge the horn furthest from us back (to the right) so it falls more in line with the horn closest to us. The coloring on the furthest horn should darken but show the horn branching away - so almost scooping away to fulfill that sense that the furthest horn is growing away from us. Horns typically align in most deer works so just creating a slight difference could help in the background.

I love what you are doing with keeping most of the detail on the foreground for the character, there may need to be just a bit of tweaking for that canine tooth to move it back and add a highlight since it is closest to that ring of light. The whisker may need a high highlight as well.

There may need to be some scatter light from the highest teal- the eye stream colors would send light scattering around the fur causing some higher lights to form but that could be style preference. Dramatic darks would also deepen the look of the light.

The whisker would cause a similar soft light cast, as would the flying koi on the fur. I think with the dramatic lighting, using some lower shades or dark tones to create more dramatic shadows could also serve to deepen the impact of the light ring under the jaw and around the neck. Causing darkest shadows in places coming towards us with the light ring causing the highest of the highs at the edges like you have done. Between the horns, there may need to be a highlight since the refraction off of the horn closest to us would send light scattering down the crest of the top of the skull - kind of like how dire wolves have a dramatic ridge.

You have a fantastic starting point and as a technical eye for my wife, I'm doing my best to try and nitpick the way I would for her. Adding a difference of tone color between the closest and furthest horn- changing how the lightning lines go on the horn away from us.

With the attention on the left of the art piece being to swoop the eye to focus on the character's face- I would add darker tones to deepen the art there as well- further making that ring brighten the focus of the eye. There may be some light scatter needed from the horns onto the ears as well, but that again is a nit pick attempt.

I may not have used the right words or be giving the right advice, but from what I would do for my wife- I hope this helps and I am looking super forward to your future work! By no means is this a shoddy piece, but in growth rests inspiration and I totally understand you! Keep up the growth efforts! Hope I helped- some more intense shadows can enrich a piece! You got this new work- you are gonna nail it!

Wow, your review is amazing, thank you so much, I really didn't think about some of the details.. damn glad you noticed the horns and fangs. Looking at the drawing, something constantly tells you inside that something is wrong. Scattered light and certain points of falling shadows are really what I need to work on. All of the above is very important to me, and I will really try to take it all into account, especially water and anatomy. Thank you very much again!
