No, I'm not expecting things to be perfect. Not in the least bit. But there's a difference between having something perfect, and having something that is at least of decent quality. You have the body down. You're GREAT at it. I just look at it and can't help but admire it. I had a couple of things to critique (that I think a lot of artists could work on). Most good artists WILLINGLY take critique, perhaps explain a bit why it's a certain way, and then try and improve.
Personally, I really like your older style, because it looks more real, and it's less warped. These tend to be very oversmudged, giving it the appearance of a horse that was drenched in oil. It'll take a lot longer, but will most definitely be worth it if you could take the time to add a bit more detail here and there, and less over-smudging.
You have ENORMOUS amounts of talent. I seriously can see you getting commisions in the near future to paint all sorts of people's horses. But... just like everyone else, you have some things to work on.
Perfection is the goal. Professional artists don't say "things aren't going to be perfect" or "no artist is perfect", because you AIM for perfection. Doesn't mean that you'll hit it, but at least you'll try your hardest for it, instead of doing half-jobs (not that you DID any half-jobs here) and then put up "no artist is perfect" as an excuse.
You can choose to dismiss my critique... or you could choose to accept it, and try and work better.
Hey... I'm trying. I'm no where near where you are. Colors hate me for some odd reason. But at least I aim for perfection, and take in all the critique that I can get, instead of just saying "no artist is perfect" and leave it at that.
