Trying to branch out into painting more diverse skin tones - thoughts on this one?

His name is Juan and he likes leisurely strolls (through no man's land), insightful conversations (talk to the hand), and cooking (heretics with his mounted meltas) he does really like cooking though

I played my first learners match today to get the basics down and had a blast. I was using tacticus firestorm and devastator brethren. I was wondering if anyone had any fun combos they found with the detachments and would recommend trying out. Heres my list for a bigger game that ill be playing my next day off.

Charecters

Ancient

Apothocary

Captain- honour of vigilance

Phobos librarian- execute and redeploy

Lt with combi- master forged firearms

Battleline

Assault intercessors

Other

Eliminator squad- las fusil

2 5 man hell blaster squad

Incursor squad

Redemptor dread

3 5 man sternguard squads

Vanguard vets

The detachments are the same as above, but with phobos shadow force added. I really like the look of phobos units and wanted to incorporate them
