Recommend to get clipstudio paint for diverse art tools.

I never even thought about colour linearts before as I always leave the black lines to help with colouring, I might have seen other artists probably use that technique so I could look into it, I also do have some books I own about art but I could use some more to learn more perspectives, it never hurts to experiment.

I draw on paper still but I would look into a tablet screen if I do have the money, although it would still be really new to me.

I'll also look into Redrubble sometime, some arts of mine would be worth selling.

Thanks for your tips! I really have been stepping up more on anatomy shaping but I still will need to work more on certain perspectives as in what setting or where do I want my character to be in, at first in my eyes it isn't easy but it's not impossible to develop more techniques on placings, angles and certain expressions they are feeling, I do own a couple books that does help give a lesson on body shapes by starting with real shapes first, round things are most common to me by far as shown in my recent draws.

I will try to step myself up on backgrounds a little more, looking at photos or cartoon backgrounds from other artists or media might help, I won't need to go overly detailed but when I feel like it, I step up to putting love on them.

I will still need work on facial expressions, I will try to look through the book I have a bit more, they actually show tips on multiple expressions.

When it comes to getting devices that helps with draws I won't need to get myself onto them just yet because of lack of funds and I still need to feel advanced for helpful tools as it really doesn't make a better artist, paper was good to start at first and I been using it all this time.

Still I appreciate your comment!

True, if you enjoy doing it and sticking to it, you will always have room for more improvement, it's what a book tells me, thanks!
