I've seen many LEGO during my time; I had the particular observation of those that are mediocre (for not saying "crap"). Why is that YOU PEOPLE don't get too much attention? Because you do not put effort on your MOC-making skills.
Here are 10 tips that may give you more success:
1. GET A PROPER CAMERA:
Not using any camera can give you the ideal look for your MOC. It's important to see the quality of a picture and if it has no flash. If you take a picture of a MOC with a flash, then it'll be disastrous since the flash reboots all over the plastic creating a shiny (although uncomfortable) look. If you want a more neat picture, use a cardboard for background cover.
2. FIND A GOOD PLACE WITH LIGHT:
Light is one of the most crucial parts of a picture. If you want to be more "recognizible", you have to stop taking pictures on YOUR BATHROOM! Taking a picture anywhere destroys the well-presented MOC. Include also that you must have light for getting a good looking MOC. Use lamps if you want to.
3. PROPORTIONS, PEOPLE, PROPORTIONS!!!!
Building random things its quite retarded; people will call you names because you can't make something good. If you are having problems at this, it's time to save money. Parts are important too, since they define your MOC and its layer.
4. PLAY FAIR AND DON'T BITE MY HAND:
For Christ sake; STOP SAYING YOU'RE BETTER THAN ANYONE ELSE. You can't compare a crappy clone with (example) a Dawn Forge Mecha from Brian Kescenovitz and say it's better than his. Stop ranting and put aside your ego: no one is better than anyone. If you want to improve your skills, then stop making crappy stuff, insulting others and acting inmature.
The secret of someone's success? Practice, Practice and MORE Practice.
5. STOP STEALING:
I won't say much, but those who steal other's people work and post it as their own are lazy liars with such LOW skills of MOC-Making. Seriously, you're looking yourself to kiss your ass goodbye from any good page that is open for LEGO Hosting. You can't do it since you're stealing someone's idea (and in US, it's a Federal Crime).
You can't just come across and say "o luk itz a gewd mecha I wanaa i wanna". Stop writting like retarded and begin to type correctly. Grammar is one of the many things that defines a proper MOC-builder from the retards like (example) Commander Marks; if you're one of those people then change! Stop writting like if you were important. NO one cares, and it's crucial to let it go!
You don't put just random sentences and stuff. You have to make sentences have sense!
8. BE BRIEF:
Don't let yourself go blown up with your ideas. Just, be brief; write down the main facts about your MOC and post it on your page.
9. TOO MUCH PICTURES ARE TOO MUCH:
Don't take like 20 pictures and upload them all on your page; take at least 8 to 10 pictures and upload them. You don't need to show all the people how many picture you took.
10. HAVE FUN!
Lego is a toy; it's nothing to get obessioned and addicted to. Of course, you can't give up. If you have problems, always have a way to figure it out. That's the good spot about lego.
Have fun and play Well!
