I am pretty computer savy, however I have very little prior experience with photo editing. I was able to accomplish this in about 4 hours of experimenting with Krita. I was pretty proud of how quickly I was able to create this scene. I realize it wouldn't fool anyone, but I still think it's fun to look at.
The program is a bit sluggish on my dual Xeon 2.4G with 1G of RAM. The filter brush worked well for some filters and either slow or not at all for other filters. This feature has great potential in my opiniion.
The filter controls are bad and interacting with the preview is slow and painful. They need to take a look at digiKam/showphoto to see how this should be done.
I thought the selection tools worked very well.
I used a layer group for the boat. The glass and the shadow have different opacity levels so I can grab the whole boat and drag it around and the background shows through.
The goose was the first thing I did so it's edges aren't that good. Actually I could use some advice in that area... "edges."
So... not bad for 4 hours learning curve... what do you think?
