Some of the shirts/hoodies look not that good but ngl you've did a good job and I really do hope this project works well for you.
I liked these ones the most which I'd probs buy if the clothing line opened etc;
The ones I dislike the most are these and i'll give some valid reasons for them;
- The typography on this hoodie looks really bad, it would match more if you had the typography of the first white t-shirt because that looks way more better. Also try match the color scheme so like if its a grey hoodie then a grey typography with it.
Overall seems pretty good but you just need those little improvements to make them look perfect!
