Here is my work in progress Counts as Pedro. Really no reason not to take Pedro if you are interested in a Chapter Master. Maybe you do not like the I1 of the powerfist but other than that his abilities vs cost compared to a normal Chapter Master are outstanding. Essential get scoring Sternguard, Stubborn, and +1 Attack Banner effect for like 20 points ~ 1 marine.
Added Basing with building bit and ork skull plus drilled out stormbolter. Next step brushed on black basecoat.
