You never know until you try, regarding arrangements. I think stabs would work well, should give the track a slight lift? And defiantly within that particular groove and style.
The second track, with the heavier, ambient, string section, could do with a smaller section patch. Chamber size , or something more dry and smaller (disco size, 4 or 6 stgs). That Symphony size seems over the top and out of context for me. Just my opinion of course, and like I said earlier, nothing to lose (other than time) reworking arrangements.
Good stuff, though. I enjoyed the listen. ... 👍
