I think that 1:14's are not bad for this combo. But anyway, the first chicane should be flat-out, that's the way I go through it. And maybe you could brake a bit later in the right-hander after the 2nd split and improve the last left turn - more throttle there and probably step on it sooner. It all depends on your setup, though.
That's my opinion about your lap. You can always check some hotlaps of the best hotlappers on LFSWorld to check the speeds in the corners and racing line.
