This little cutie in his tub is from stamp set 103 Baby #2. This set has 4 sweet babies in total and an accessory stamp.
My image is coloured with Prismacolor pencils with sansodor and paper stumps to blend. I have added Sakura stardust to the bubbles. I applied the stardust to an acrylic block and lifted with a damp brush. The sparkles are not showing well on camera but you can see them a little in the below close-up.
