Looks like a good start to me. Furioso with the Frag Cannon in a drop pod is a classic choice and does great work earning first blood.
Librarians are good for blood angels. Biomancy and Sanguinary power charts are both quite nice.
Tactical squad and Assault squad in pods are also great. I'd make sure that the assault squad has two meltaguns (when you have the points in larger games) and the Tactical squads in blood Angels are great with meltaguns and heavy flamers (as only Blood Angels get heavy flamers!)
From there, Do what you want. Combined arms detachments are nice, so your tactical squads and their drop pods are objective secured. The Codex detachment is also nice, granting you a bonus to initiative on the charge (which is nice with furious charge).
I would make sure if you want more pods, to take an odd number of them, but I wouldn't take more then five (that's a bit much I think).
While building your army, just try to think of how you'll deal with possible threats from other armies. How will you deal with super-fast assault armies? Shooty armies? Lots of tanks or 2+ saves? Hordes?
Adding in units with unusual deployment is helpful too. Drop pods are great for that. Infiltrate and outflank can also be useful.
You could be easily outnumbered, but you'll have great ability to apply pressure where yo want and withy Drop pods, put all your army into only part of your opponents.
If it was me, I would add in a second Tactical squad and a tri-las pred or stormraven (to make the army legal and then add anti-tank) That'll leave either 70-100pts to add what your want (upgrades, attack bikes.. whatever).
Here is how I would expand your army.
1000pts
Librarian (stock) 65
Tactical Squad 195
x10, meltagun, heavy flamer, drop pod
Tactical Squad 195
x10, meltagun, heavy flamer, drop pod
Assault Squad
x5, x2 meltagun, drop pod
Storm Raven- 200pts
Lascannon, Meltagun
935pts total (leaving you 65pts to play with
Nothing starts on the table Turn 1 (which is cool!)
Librarian deploys with the assault squad.
Ideally, Dread and either assault squad, or one tactical squad comes in Turn 1 (to either flame a few things, or flame one thing and pod a tank). Storm raven gives you good anti-tank and anti-flier. Last points can be put into upgrading mastery level on librarian and some random upgrades on sgts. or buy a fifth empty pod as a fast attack slot, so three pods can come in turn 1.
For 1500pts, I would add the fifth pod for sure and some sort of assault element. Death Company or Sanguinary Guard. I would also add a Sanguinary Priest to give Feel No Pain and +1 WS to the assault unit (and jump pack). Then for extra points, it doesn't really matter. Nothing is really terrible in the codex.
