I hope you don't mind me tweaking your art. All I did was adjust the values so that the characters better fit the lighting in the scene AND I cheated a bit so that the llama's head was more of a focus. The first pic is your drawing in black and white. Everything is a bit flat. Nothing is dark enough or bright enough to focus the viewer. The next is my adjustments to the values. Final pic is just what it looks like WITH color. Nice drawing!

What type of style are you aiming for? Who are your favorite artists? It's hard to critique without knowing what direction you want your advice to send you.

Helloo :). I like this a lot, very colourful and happy :D. I would say though, that the lama's tongue gets lost a little amongst the woman's clothes. I would either draw it so that the tongue is against the background some how, or, make sure that the woman's clothes are a more contrasting colour/shade. You need to be able to 'read' the image even when squinting. I like her expression :D
