Hey, it's your work and you decide how it works best for you. Over the last few years, I've noticed how much more critical I am of the choices made by mappers in terms of labeling, layout, including important sprites like visible weapons, items and bosses, etc. Heck, I'm often critical of my own past work, but I lack the time and motivation to go back and redo them. Besides, I'd rather not start going "George Lucas" on said work if I can help it; the urge is there to "fix" my "mistakes" but I try to keep it in check since said "mistakes" are simply different choices I made back then and would be likely to change again sometimes in the future. Better to keep the past as is.
Going back to my comment. There was a time when I loved just about any well assembled screenshot map I would lay my eyes on, but as I grew in experience and as my tastes changed, I started noticing little things that I would have done differently, little annoyances that made me wish I had the time to do those maps all over again but do them "my way". Of course, that would be completely *nuts* since the list of games I'd want to map again myself keeps getting longer as I get pickier. So, consider my comments for what they are, personal suggestions but nothing more. You already did an amazing job mapping that series and you've certainly achieved your goal of making great-looking art.
