H: Some things W: Some other things.

You should take a look at my own Selesnya deck, we're building in a very similar direction. Some ideas for yours based on my experience:

Seller of Songbirds should go. It looks attractive because of the evasion, but you don't want to waste your mana populating 1/1 tokens if you can pump out more 3/3s or maybe 8/8s. It's great in limited, not as useful in constructed. Doomed Traveler isn't terrible, but in this context I'd put him on the sideboard in case you need to get out fliers fast. With your removal package, though, you really shouldn't need any further counter to evasion creatures, so I'd almost say you can do without him.

The fog effect you get from Druid's Deliverance is also a little tricky. With limited slots in the deck, I'd rather play something like Rootborn Defenses in my main if you're intent on the protection mechanic, so that you could spawn another blocker and then blindside your opponent by blocking with creatures he now can't trade with. Druid's Deliverance just prevents the damage to YOU so you have to let them through and you don't do anything to the board state but add one creature. Better yet, I'd play one of the populate spells that already creates a token of its own, like Courser's Accord. Gives you two more creatures with the option of making one of those a copy of something even better that's already out. That in combination with Grove of the Guardian has been badass in the mid and late game for me.

Last thing I'd say would be move the Smiters to the main. With your acceleration creatures, droping a 4/4 on turn 2 would be devastating and let you put on some pressure or hold off an assault while you get your tokens pumping. I've been trying to get a playset of those myself to do the same.

Anyway, those are my words of wisdom from a fellow Selesnya member. For the Conclave!
