In honor of the 100th thread. Phone and tablet rice. All in one.
>>1722717>>1722720I like the purple. To keep with the pink theme you originally had using the dark pink from her sleeves may be a good choice as well. Keep the blue background. All those colors you mentioned except for very few select shades of purple will be a harsh contrast.
I'm not too good with gimp, I use photoshop more.
To add the shadow in gimp make sure your banner layer is the current active one. Some where under the filters under light and shadow you will see drop shadow. Just play with the direction and make it point either up or down so its above or below the banner. I would start with above so the shadow matches the shadow from the nav bar.
