ATos - Never seem to get it quite right

[Roadstar]

I've taken on more of a raise or fold mentality with ATos. Is the raise preflop and the call (and calling the raise) ok here?

Table is LPP city. Peculiar C/R by UTG given hes > 40% VPIP w/ 0% PFR over the last 12 hands (extremely small sample I know)

Thx
