Well, if that's your first attempt with Prismas then it's way better than the first time I tried to use them, rofl. I like the colors you chose!

some marker attempt
this is NOT a marker attempt
this is marker mastery! XD
this is really good i love the look of it

I have some tips for you!
When using markers I use a special bleedproof paper so that it doesn't bleed ouside the lines and the details come out finer.
Also, I can see the strokes you've made - to prevent this you should colour quickly & in circles, not strokes, it'll make it much smoother.

Also, yes, going over it with pencil will help if you want finer details like fur :D

Good luck with it, I personally love markers c:

OMG
That's awesome D:

this actually looks pretty neat! :3

damn *concedes* If thats an attempt I'd love to see when you master it.

Looks very serene. I like it. :X)
