some logo sketches for my new clothing brand

They are looking good but I would try and keep all lines and edges and minimal as possible for clothing designs unless your are going to use dies or graphics in the center of tees or hoodies. Stitching or small logos loose a lot of detail when they are complex and sometimes do not look as good when applied to the clothing or other merch... So simple and bold in a single or 2 color scheme tends work best.
