That's really good Owls.
If you enjoy art then I say go ahead and draw.
I'll give some tips for next time or to learn if you wish to. Dinosaurs have the problem of not having living references to work off of, all we have is bones and such, still I would look up real dinosaur bones or realistic art from other people and try to learn from them. All art is based off real life everyone just changed it up for their own purposes. I would grab some pics you like and draw shapes over their bodies, this is tracing yes but you are not posting it you are only trying to understand how this is built, reverse engineering as you will. You can brake the rules of drawing if you know you are breaking them, ie I'm sure dinosaurs couldn't make such expressions with their faces but most people break that rule cause they want to and it looks good.
I'm still trying to figure out how Carnotaurs work. It's a little hard, but I'll get there like you will. Keep drawing you get better the more you make.
The lineart is the best part of your piece it gives it a hand drawn feel and it looks a bit like a animation cel. The only things that bug me is the tail and face, tail should tapper off more and the face looks off I dunno maybe the head is too small or the expression is off.
Maybe you should try shading next time? What art program do you use to draw? I use Firealpaca for my work.
