i'm not good at commenting 'professionally' but i want to express how much I love this so much.
1) I love the way you draw the backgrounds, those tiny details like the dotted highlights is unique , making the background very enjoyable to look at. 2) the colors!! its my favorite of all. it really looks like those from vintage illustrations.. and it really shows that in here! <3 3) the dog's pose are just so dynamic, i can feel the dog's jumping right now in from my eyes!! I love the light strokes on the dog, its special for me.
in conclusion, i pretty much love this. <3 actually i love every drawings you did, its just inspiring.
sorry for the long comment, forgive me if my English is horrible x_x
