TEXT are kind of small considering you have a bigger canvas. All in all, i really like your stuffs (checked your portfolio on behance)
Also, if you're making thread designs here in MPGH, there's a standard width of images that can fit the entire post here, like what i did on my thread design here:
https://www.mpgh.net/forum/showthread.php?p=14999957
it is 916px, but you need to divide it by two, so it's 458x(length) by 458x(length)
Just check the link so you'll have an idea to what i mean.
Good stuffs!
