My one bit of advice is to make your motifs on the larger size. My motifs were 1 1/2 inches and as any Photoshop fan will tell you you can scale down with good results but you can not scale up. Once you have finished with your motifs scan them into your computer at 600dpi or higher. I find the higher the better for a cleaner image.
Take a look at what I came up with, below. I am so pleased with the oil paint look of the motifs, let's see what you come up with.
