Need help with regarding scaling....or maybe paths?
Ok, so I found the first image online sometime last year, that I wanted to use for a project, but after dozens of tries, it just wasn't working like I wanted it to. After some months away from it, I decided to come back and try again. My thought this time was that it's the rounded off pink and blue outlines that are just not what I want. So my idea was to instead remove the rounded off outlines, and instead redo them in the same shape as the spider emblem, as I really like having the colored outlines surrounding the spider.
Well because Photoshop is just to expensive now, I have resorted to Gimp, which I have very little knowledge of. Basically what I have been trying is duplicating the spider emblem, and then scaling up (and down) to recreate it. Obviously since I am here, that has not been working out, and I have tried several different things like edge-detecting....which sort of works, just not the way I want. As you can see in the other image, the scaling just is not working how I want where its shifting the shape. So can anyone give a Gimp n00b some advice? It would be really appreciated.
