Hello.
I have created my first shirt using my phone and Medibang art. It doesn’t look great from what I can understand, but I think as a first it stands as great reference.
I do find that the back logo definitely needs to be fixed, same with the rough edges. But are there any other things that require fixing? Your feedback will definitely be appreciated.
First shirt is good, I have not much to say since it is your first, but put more time into all of it rather then parts of it, it looks like you used the brush, maybe a better painting software? It doesn’t look so finished add more detail rather then that first shirt is good!
You did not have to erase the entire template, only the fields where you design the clothing. Also, setting the quality to 1% defeats the purpose of requesting feedback.
I think your shirt is pretty solid for your first run. Although I would use the line tool to make the lines more smoother. But this is still a pretty solid shirt!
