General Critque - Can you make your pictures bigger? Hard To see.
From what I could see I like your style, seems fun and storylike. I think you are strongest where you take the illustrations back to people - ie your last pic. A wierd thing or creature in isolation is very easy to dismiss as a doodle. There's nothing wrong with doodles but IMHO the evoke less reaction and are forgotten readily.
My favorite is the purple, teletubby terrestrial looking creature. The shining flesh, clouds, eyes, and position make for a fun character. For the rest, you can cut down on using the color pink and bright colors that direct attention away from it. Your cartoonish style is looking promising.
Keep doing you
