I have a couple of time lapses up on my Instagram if you’d like to watch them! I’m not sure what you use you edit (I use Pixlr) but for me it’s definitely easiest to paste all the parts you want into different layers and then arrange and erase them as you go.
And I also attempted a peace sign! I used the method that @Davideogurl described and it went really smoothly! When I was figuring it out, I looked at this post for reference and found it incredibly helpful:
If you’re looking for other suggestions to improve your edits, one thing you could do is fix little details with the clothing. If you zoom in on the model, you can see where the line breaks at the top of her dress, as well as some extra lines that will appear around the waist/elbows (for animation purposes). I wouldn’t necessarily smooth out every line, but sometimes they’ll break up an article of clothing where it wouldn’t be broken up in real life. I don’t think this tip is as relevant for this edit, but it may come up in other edits down the line (I find it happens a lot with pants haha).
Finally, you could focus on little details to really elevate the edit. This can be creating additional highlights and shadows for more visual contrast, or adding your own drawn elements like jewelry/tattoos. Personally, I really love when people add hair details, even if it’s just a few wisps of hair.
I basically completely color over my edits to create skin details. I add shading and highlights to make them more “artistic” and less “episodian.” Really this a personal preference, though. Your edit looks very nice. Most importantly, you need to be happy with it.
