As a fellow Son of Sanguinius, allow me to say well done sir!
That is an excellent conversion given life by a beautiful paint job! Kudos on the excellent paint work and decal work too on the cape!
I personally field the 5th Battle Company of Blood Angels here, and did up Captain Sendini (my own conversion) of the Daemonbanes. It's awesome to see others takes on the established Blood Angels Captains from in the fluff and lore, and I can say that I do prefer your version to the one
GW version that was done up previously and painted using some of the same bits. I absolutely love the Iron Halo bit too that your friend added also, as an aside.
Exquisite paint work as I said. Also, LutherMax, if you'd like to check out my Captain Sendini mini, I have a few pictures in my Gallery under the Finished Blood Angels section (Last page/earliest finished models), just look for the wings.

I'd love to get your feedback via
PM if you'd be obliged to compare notes on paint work.
I can't wait to see more 2nd Company Blood Angels if this is any indicator. Take it easy and thanks so much for sharing sir.
