I agree with Kevinb, it looks like a nice high white spider. I would hold onto it for a bit and see if the white brightens and the yellow comes down a bit. As for a spider though the ones that are higher white with the greenish coloring are more like the original from what I've seen. There is a picture of one like this in McCurleys morph book on page 189 that she could turn out to look like which would be really sweet!
