My prior Spanish warband was Gripping Beast Normans painted in a yellow and red color theme. I much prefer these Crusader Miniatures. If you're going to paint Spanish, do have a look at Crusader! I used Stronghold Terrain's metal bases with rare earth magnets. Love 'em, they really hold fast to the bottom of my transport boxes!
The last pic is the start of my display board. My crackle-board experiment was a spectacular failure. It turns out you can apply crackle paste too thickly and it took a week for my board to finish crackling. I applied Liquitex Matte Medium liberally over the crackle to seal it. I put it on too thickly and after it set, it became a mess. I couldn't save it with sanding and cutting so I binned the whole thing. No worries, Plan B is under way.
