It's always interesting to see how people start a project. You've come a long way with this one and I like your willingness to adjust your stuff. Let's put them all side by side for comparison.

Alright so. The first three were done on your own and the last one is the stripes on an already made T-shirt base. The only problem I have with this method of learning is that your just "stamping".

Before I offer any critique.

Do you see the differences in how the palette has been used in the latest one compared to the others? What do you notice that's different between the items?

@Ziggy: Those long Striped tops are interesting. Kinda temped to try one in the future but they don't fit the current themes. Something to put a pin in for future stuff for sure. :D
