Your art is inspiring and lovely. To echo what others have said already, your website portfolio is CLEAN and shows a great variety and range of your subject matter.
The only thing I would personally change, as others mentioned, is either separating the two mole illustrations (or removing one). I find that they don't contrast and "look more of the same." Also can be said of the 8th/9th illustrations with the green shirted creature (it's not a koala bear... is it a possum?) - If you're looking to cut down your number of images, one of those would be my suggestion.
With that said, I found scrolling through your portfolio very enjoyable. Excited for you!
