First, I think you are not casting DE nearly enough. On almost all the logs I looked at about 20% or so of demon summons are not followed by DE. That is costing you a massive amount of damage. There are several times where you Grimoire:Felguard and don't cast DE at all, reducing the damage it will do by 50% or more. Same thing with doomguard. As a general rule following any demon summon you should be instantly casting DE, not waiting, not casting demonbolt etc... The only real exception to this is if you can back to back cast demons (ie call dreadstalkers into immediately casting a full hand of gul'dan). On botanist, compared to my log, we took him down 50 seconds faster, yet you cast DE 1/3 less. This is probably your largest issue.
If you have trouble keeping track of DE, or your demons in general, download Not's WA for demo (linked in his post). It is almost mandatory for playing the spec correctly and tracking your demons/buffs.
Second issue I see at times is wasted shards. In the botanist fight you "wasted" 31 shards. You can see this by going to resources, and changing to shards. Each shard represents an imp through HoG, which will pump out 200-300k over its lifespan. So there is another 5-10 million dmg lost on that fight. The other fights were better in regards to shard management, so maybe this was a one off. If you do not have the add on "doom shards" I would get that also.
Third is buffs/consumables. It seems like you are not using a flask/food and consistently pre-potting/potting during the fight. Missing the flask is 1.3 k intellect. which translates to roughly 13k dps. Good food buff can add several thousand dps. You are probably missing 20-30k dps by not flasking and potting. Which is a super easy way to add damage.
Fourth is talent choices. Except for pure single target impending doom is a better talent compared to improved dreadstalkers. Basically every fight but Krosus should be ID. And even on ST it is not much of a loss. You are losing a ton of cleave damage on Spellblade, Botanist, Gul'dan and Elisande.
These are just some of the bigger things I noticed. You can also try experimenting with different builds (like darkglare), but they are more "complex" than the generic Demo build and I would work on mastering the basic play style first.
