Thanks for your comments.
I know the 1/144 is not popular as 1/72 or 1/48 scales. The current "new tool" model kits are quite detailed and comparable with 1/72 kits. Another advantages are many decals options available. The Syhart decals are excellent quality - about 50 markings and stencils were applied on this kit. That makes good impression.
Generally I follow with two rules:
1. 1/144 scale models are as other scale kits - if you feel something should be detailed, changed or corrected just do it!
2. There is no place for mistakes. Any error will be multiplied by 144! So, if building or painting goes wrong start again, again and... again. For example the fuel tanks were washed and painted 3 times.
Two examples of corrections. ECM equipment (scribed bay for flares, extension for chaff added):
Fuel tanks (panel lines corrections, raised lines were made cause of welded tank):
