Im not sure if youve done anything but the centerpiece is a bit big, so try sizing it down a bit

the background (imo) clashes with the the centerpiece, i would personally integrate preexisting colors into the bg. this can be achieved by finding something with hints of those colors or making your own using this photobashing kind of technique that i personally use where i take photos and use different filters (ex: overlay, color burn) on them
a nice border would be good, but as i replied to one of your other asks, take your time, and look for inspiration. this is really creative already

it looks so large on desktop... anyways, maybe a border?

Okay so I love the style of it but most of the things I’m about to nit pick IS personal preference

1. The background doesn’t match the whole general graphic so it looks kinda funky since a yellow-green doesn’t exactly match a red-black
2. The graphic is a bit too small for the frame so it looks weird too

By the way the first one is more so pref but the organ look does look nice. The colours just don’t match with the graphic

MARISKA!!!!!!! EEEK.... I think it looks really good so far!! Maybe you could try making the picture a bit smaller so it fits in the box? :D and I think if you added text to it it would look really awesome!!!
