Having fun with digital photo and GIMP

I spent the last hour GIMPing around with a photo I took a couple of weeks ago, featuring my best friend blextar and me with the most stupid and arrogant face we could ever think of. My auntie has bought a new camera, so she gifted my family with her old one. It was a long time I had been thinking of buying one, and I got one without even asking! What a luck ;) The photo is one of the first I took with this new toy. I wasn’t satisfied enough with the original one, so I thought to edit it. I messed around with all possible mix of plugins that came to my mind. I am attaching a couple of results. The one I like most is blueish one. To achieve that result I followed these steps:

1. <image>>filters->colors->decompose->CMYK
2. <image>>filters>blur->gaussian blur(RLE) (12px)
3. with tool "select by color" with thereshold around 80, I clicked on light part, floated the selection and anchored to a new layer
4. with the new layer selected: <image>>layer>colors->posterize with 15 value
5. <image>>image>mode->RGB
6. mess around with <image>>layer>colors->color balance to get a nice blueish photo

If you like challenges, you may look and try to find which instrument he plays.)
