I will agree, the Poliwags are indeed very nice. However, I think there's a lot to say about your more recent update as well.
First off, Sylveon. Let me say that I am absolutely, drop dead jealous of how well you can draw animal feet. Those little legs are so perfectly matched with the body, they line up perfectly with the "ground", and the individual toes are spaced immaculately. It may seem weird, but that's initially what attracted me to this piece. xD It's true though, I struggle so much with drawing animal legs/feet, so seeing Sylveon's anatomy drawn so well is a real treat. Next, it's obvious you're going for a more illustrative style as opposed to classic Sugimori, and I respect that. But there are a few things you can do to build on that a bit. For one, you're shading is a touch off. Not in a bad way since lighting/shading is interpreted differently in each piece (let alone each artist); but you have light hitting Sylveon from a bunch of different angles on the body, save the upper thigh. It's just something to be mindful of, not something that needs fixing. :)
Now, Sylveon's body seems to be angled odd compared to the angle of the face. Make sure you're drawing your guidelines while in the sketching phase, cause it'll prevent stuff like that from happening. Or it could just be that Sylveon's face is placed high on it's head. Again, just something to be mindful of. Speaking of which, I very much like how you decided to outline Sylveon with pinks and blues where appropriate. It gives the drawing much more visual appeal, in my opinion.
Overall, I very much like your new Sylveon piece, but I think we both know you're capable of much, much more. That said, as just a practice of new techniques and considering your tablet complications, I'm very impressed.
On to Victini! :D
Again, the body is drawn very well, but Victini's head looks so oddly placed on it. I can't tell you exactly why that is though. Maybe because the head/face is too small? I feel like Victini should have a head to body ratio of 3/2 (including ears). Anyway, I can say that I love the brush strokes you've decided to use on both pieces. It makes it feel authentic to you, which is something I feel is very important to an artist. Speaking of which, the shading on Victini's left.. thigh.. wing (thing???) seems blocky compared to the rest of the coloring. But you may not be completely done with this drawing, so pay it no mind if you're still working on it.
Overall, Victini feels a bit rushed to me, but there's nothing wrong with that at all. Heck, sometimes pressure is a great tool. xD But if you have the time, mood, ability, make sure you're thoughtful about every line while still keeping the bigger picture in your scope. You'll find that it makes for a better result.
Tara, I think you're progressing at a good level with your art and you have a lot to be proud of here. You're working hard and it's showing, although you may not always be able to see it. Don't forget to draw your guidelines and use references and, above all, don't forget to come to me if you feel like "something doesn't look right". I'm happy to help however I can. Just keep working at it!
okay looking back this post got waaaaayyy too long, sorry! <3
