It's looking good! I really like the painting on the snail, and the changes to his face. The speckled patterns look really interesting & add to the character of the snail.
I'm feeling conflicted about the clothing on the rider. You have a hat that he could have just found on the ground, clothes that are either well-worn or rough-hewn, but have bright colors, and a satchel / saddlebag that looks well crafted. The shoes are less noticeable, but they look like they'd take knowledge and skill to make as well. The two characters are very whimsical and fairytale, but the shirt looks almost like a t-shirt. I think this discrepancy--along with the bright colors--draws attention to the clothes instead of the characters. I think even just changing one thing or the other--the style or the saturated color--would reduce the distraction.
Maybe you could think about the world this character comes from. Does he have to make his own clothes and items? Are there skilled workers? Does everyone dress the same, or does it depend on their job / lifestyle? You can have a mix of shoddier items and well-made things, but if you have a story / background behind it--that can help it be more cohesive in your view of the character, and that will come through in the drawing.
