You are doing alright with your artwork, need a little work with body proportions, giving the arms and legs a proper feel to them and making all the joints work. Your coloring is really good, shading could use a little work, you got a few shakey lines in the shading here and there. Other than that, your art is really really good.

As for things to draw, Anything you feel like drawing dude. Whatever ideas you find to be clever or cool to you at the moment. You could try drawing with a theme, I see you like TF stuff, which is always nice.

Thanks for the critique and compliments!
Yesh, I do love TF. Though, sometimes I have a block and can't think of what to do.

I'm always gonna say Ottsel TFs. Ottsel Day is right around the corner on December 3rd.

Or what about Dinosaurs?

TF is always a nice thing to see, but then you can draw whatever you feel like drawing. Try closing your eyes and drawing the firs thing that you see in your mind.

Species...I have a weakness for donkeys but there's so many different species that are so cool. Felines are nice, canines as well. And I've recently noticed that some other species like beavers are not as popular as I would've thought, I haven't seen that many beavers lately.

Skunks, by far. Some of the hottest transformations from come from smelling the scent or getting sprayed.

I'd say your muzzles do need some improvement, they often come out looking too long and pointy, not quite natural. Your footpaws often have slightly oversized, bulgy toes as well. Those are the most noticeable things I can critique.
