Latvian law reads as follows:
Straightball (Airsoft) weapons with an initial projectile energy not exceeding 1.5 joules

I would say that looks good but you could fit twice as much cover / barricades / buildings in that space!

If you imagine it like a village with 2 meter wide “side streets” and maybe one 4-5m wide “main road” (with maybe a road block / check point on to break it up)
 
When you are laying it out make sure there are some interesting angles on the roads / alley ways to keep people on their toes!
 
Keep us informed as you build this site, looks like it could be a great semi-urban field 😀

Yup agree with the above comment , to me this layout looks like your everyday run of the mill American airsoft field that you see on YouTube all the time .
By the look of it to me you’ve tried to lay the obstacles out as randomly as possible ?
id recommend going for a more formal ‘city block’ layout my self , a centre ‘main road’ (with an open area in the centre that has a large bunker or something in the middle of it) and the other obstacles zigzagged up the sides of this centre ‘road’ .
id also build two extra ‘base’ areas one in the large open area to the right of the field and the 2nd in the small corner angle to the left of the field .
But that’s just my take on it , keep at it and keep spreading the game ! 

Looks like a speed ball field. Yawn

Entirely not my style, but as said above. It needs a lot more cover. 

I would look at digging in some trench systems as well, to give it some variety. 

Personally, I would want to see a more built up mini village, than two houses and some barriers in the middle. 

That's going to get really boring, really quick with just a line moving back and forward.

Sneaky flanking routes are non existent and locking down areas of that map will be super simple with a half confident team. Meaning everyone is soon going to get all pissy that hey cannot move forwards and then all the shit starts. 

Had a quick play about with your layout from my perspective of what I’d like , gray is all open space no obstacles on it .
