Jinx? Stands for Jinx! Durr.
those are really good! they look really realistic. i do agree with you on how you say the first one is the best because it is! the outline is done very smoothly. also, the light shading done on the petal crown makes it looks nice. the shading done on his knees also helps.
i think kitturn needs more work because of the outline isn't as smooth, but i think it is because of the fur effect that you're going for. you can always try to make the outline more smooth and then shade in some fur which might make it look more nice. also, i think the eyes need more shading because it just looks like big shapes to me.
nicely done, can't wait to see more.
