Very simple, The top three seem like good logos. For the first you should make the stroke of the background bigger. For the second one just fix the G and its great. For the third I think the Store text should be a different color, thats it.
BUT for the last two, they are too simple. They need some better effects. For the second one move the two up just a bit. The last one just looks like text slapped onto a background.
@azryu thanks for the input. For myself i like the 1,4 and 5. :D and second G must change. currently not in mood of changing. Too many site to manage. :D
@rafiag yes, superjstore is my another online shop in our country. Qoo Market is the oldest one. have a lot of memories. :D
@emzal i agree with u. i just too lazy to change. LOL
