You’ve just solved a problem I was having about aligning diagonals on a shaped surface.
I'm happy to hear it! Considering the countless tips and tricks I've picked up from CMON (and the whole online painting community), I'm glad I can pass on a few of my own.
I'm preparing to move at the end of the month, so I'm putting my tiefling project on hold. There's still lots to do and there's no way I'll finish it before I have to pack everything up. Therefore I decided to work on a project I actually had a shot at wrapping up before July, Brom the 1/35 scale dwarf. I've now attached the hands and club and began painting the rest of the arms. Still need to do the skin on the hands (just base coated at the moment). I also worked on the back, taking care of the weathered armor and a few other details.
I also did some more work on the base. Previously I'd built the broken bridge, but the surface of the base was just bare cork. I used a modeling compound (bag of white powdery material from an art store + water) to create the dirt shapes. While it was still wet, I pressed some rocks into it to create the rocky looking ground that I wanted. When it dried, there was not a strong bond between the compound and the rocks, so I used a few drops of super thin super glue over the rocks (one drop here, one drop there). It quickly spread out and soaked into the base, forming a nice strong bond. Over top I used some white glue in places and sprinkled sand for further texture. I've done this a lot and have found pieces of the sand can get knocked off while painting and handling the piece. So I decided to use the super thin super glue trick again. Worked like a charm. As a bit of advice if you want to try this, super thin super glue flows VERY easily. Carefully let a drop fall out and onto the rocky area. It would not be hard to accidentally douse your base in the glue. It also spreads out and soaks into the base (if it's porous), so start nearer the center of the base and work your way out. It's easy to get this glue where you don't want it, so just be careful. Oh, and should you use baking soda for texture, super glue (thin or otherwise) will create an exothermic reaction. You'll see some vapors rise and hear it and, should it occur on your skin, it'll hurt! If say a bit of the baking soda got onto a paper towel and you used that paper towel to quickly wipe some glue off your hands, that would create an unpleasant surprise for you.
Well, after all that I did a little painting on the base. Got the dirt color down and am now starting on the stones and bridge details.
