New Skills for N!Hawkeye

I’m F2P and this Hawkeye has been my favorite unit since making this build, but I think I can improve it and I’m sitting on some nice fodder. I have Laguz Friend 4 and Even Atk Wave N, which I think goes well with this build?? Not sure. Would appreciate some suggestions from people who know this game better than me. Either way I’m open to suggestions. Would this make him better/Are there better options?

(I realized after writing this - I also have A/D spiked wall from the free Ash. Is that better than LF4?)
