Is my list just lucky? 1500pt undefeated

So I am pretty new to DE and just came back from a 10 year break from Warhammer. Picked up DE because i like the style of the army. Only played a handful of games so far but I have't lost yet! I feel there is more I could do with this list and I could bare to make some changes. Maybe more anit-tank? I'm not to sure to be honest. It's worked well so far but will it last lol! Any CC very welcome! Thanks for reading folks!

Dunno, man. What've you played against? Your wych squads are pretty large, do they usually perform as well as you'd like?

I'm new to critiquing things, I'm not all that confident myself. Critique of my critique welcome.

I run a very similar list at 1850, and mine was unbeaten till a recent loss to crons, it's a well balanced list so I wouldn't say it's just luck, but it's far from a powerhouse list. Fun to play though
