As far as it goes you have made a good start,
How far do you want to go.?
You could fit "ABER" Engine Grilles and a proper pair of Headlights to replace the monstrosity's you are presently displaying and it is no fault of yours that you have the redundant Aerial stowage tube on the Left flank (as viewed from the rear of the Tank)
Heng Long do make a nice affordable Tank but they come with faults, although the excessive number of Aerial stowage tubes is also to be found on Torro and Taigen Tanks.
The size of your pocketbook will decide how far to go.
Have a look at some of the builds on the HENG LONG Builds section of the Forum and you may come to the conclusion that some of us are suffering from an obsession in detailing, such as accurate decals on the obligatory Fire extinguisher and replacing the Radio Aerial with a "Shumo" or "Aber" alternative and the next thing you know you are buying "Voyager" or "Aber" Photo Etch and buying crew members and painting exquisitely detailed uniforms upon them and then comes the Metal Tools and metal Tow ropes and of course you will definitely need at least 20 Wing/Butterfly nuts,
I sometimes wonder if there is a limit to what you can do?
And that is just the outside, New gearboxes and "Clark" or "IBU2" control boards are a beginning for working on the interior.
and You might like to fit a "TARR 2" smoker and new upgraded speakers.
Sometime soon the funny farm beckons or the Bankruptcy court
Whatever you do, please never forget you are doing this for FUN, If it becomes like work I suggest you STOP

I went from 1 to 3 very quickly.
