Make-Believe Mushrooms and Asking for Advice

I wanted to play around with the mushroom dies I bought months ago, and here's the result.  I intensely dislike the photo, which looks so gray and dreary in the full card picture. I had to buy a new computer (the last one gave me 7 good years, I think) and don't have Picasa photo-editing on the new one yet. I can't brighten the picture further without it looking incredibly artificial.

Picasa is no longer available, so clearly I'm going to have to do something else. Recommendations, please?

These 'shrooms bear absolutely no resemblance to any naturally-grown fungi. But they sure are colorful and cute! I scribbled Arteza brush markers on an acrylic block, spritzed with water, and stamped the paper. A little heat from a heat gun dried the wash quickly, and then I cut the paper with the dies. I added the dots using my little StampinUp speckled background stamp. The sentiment is from Papertrey's Sign Language set.

It's been a crazy week with planning and taxes and such, but I hope I can stamp a little more this week.

Mercy, grace, peace, and love,
Susan
