Cosas, thanks, I asked for side view, because the landing gear seems a bit off, hope you do not mind the feedback.
If compared with the pictures in the links below, front gear is too much to the front and its supports too much angled, main gear is too much back and main gear covers, that cover the wheels are a bit wrong too (should be larger and more rounded).

- the 2 above show its fuel tanks, laser guided missiles and probably a targeting pod loads, could be helpful for various pylon shapes, if you mean to get into that at all.
In general, I would say the landing gear and the main gear covers look quite similar to those of the other Mirage aircraft with delta wings - III, V and mostly 2000.
Hope that could help you.
