Looks good, I especially appreciate the hand painting on the banner. I see a lot of old and Forgeworld parts, like the Mk. III helmet and the Apothecary's backpack - I have one of those in my old Marine army, from years and years ago.
the amount of detail is stunning and every mini has it's own individual heroic style, a dream command squad for every ultramarine collector...i really like the white cloak and rope on the AOBR commander and the spartan looking mini on the total right is also kickass, the freehand on the standart is mind-blowing too...man i love it in every way
The darker shade of blue, the kind Crimson Fists have, looks oh so much better than the normal Ultramarines smurf colours. The standard bearer and sergant would probabbly have to be my favourates, but to be honest, i'm surprised you didnt convert the commander any more than a simple arm-swap and skull probe. I also like how you snuck in Sicarius's helmet. Overall, an awesome job!
Cheers, that effect was not entirly intentional, the new pots of Regal Blue paints from games workshop are less rich in the blue colour than past pots of paint, the mix is using current regal blue with mixes or enchanted blue and ultramarines blue to get a close enough colour to the past Regal Blue "sigh"
well the best way is to use a all purpose superglue as well as "pinning" the joins of that beastie.
I find using black undercoat good and following the "how to paint spacemarines" as a good starting point, as for the ultramarines i have managed to perfect the mixes to a level where i recognise the right colours.
