doesn't necessarily looked twinned to me. Rather it looks like you have a trigonal or hexagonal cell with a long c-axis. On image 2 it seems you may have systematic absences along l, although it is hard to tell the order. Perhaps P31, P32, P62, P64 or spacegroups with these symmetries plus 2-folds perpendicular.
