Hey, I would want some help.
If I would want angel wings in the shops. how could I request for them?...

I realized there are only spikey and colored wings but no angel wings

Angel wings would never be a shop item. No site would do that as they're a highly sought-after item on any avatar site and will always bring in much needed revenue :)

However, if you'd like to suggest shop or contribution items we have stickies in Site Feedback specifically for doing that, you can find them,

Here --> Regular item suggestions

And here --> Contribution item suggestions

I'll be locking this up now, but feel free to post your ideas in either of those threads :)
