*For 10, I really could not find the right way to write "what can we eat?". its -ebil, and a question. or is it better to use -ebil + ecek, and would that be "what will we eat?" 

 uzun boylu is usually used for people, not buildings. It would be more usual to use "yüksek binalar" for tall buildings, or maybe even "gökdelenler" for skyscrapers

Take a look at this again. I think it is just a typo: because you put ´ you knew you had to put an ending on the word İstanbul ....

 These both sound a bit odd in Turkish.

For # 8 it would be better to start with siz, as that is the one who is waiting. You then need an ending on uzman to show it is one being waited for. Burada fikirlerim "smells of translation", Turks wouldn´t naturally say that. As a native English speaker, probably what I would write would "smell of translation" too, so a Turk would be better placed to really do a natural translation. But I will try:

Siz bir uzmanı beklerken, fikirlerimi sunayım.

#9 It is seyahat (spelling mistake) . If you put a -yi ending on cadde it becomes the subject not the object, so you need to say "they will finish the new road":

Biz seyahat ederken, yeni caddeyi bittirecekler

Or make the cadde the subject and say it will have been finished:

Biz seyahat ederken, yeni cadde bitmiş olacak

 ne yiyebiliriz or ne yiyeceğiz would be OK

 işi almak sounds wrong. iş teklifini kabul ederse sounds better

Mavili, it seems to me that you have taken a Big Step forward.

Thank you for the compliment Abla, it truely means alot from you. I feel i´ve improved some but there´s still much I need to work on it seems. 

I understand the first part, with the how siz should begin the sentence. But what do you mean by saying it sounds odd in Turkish? If what I wrote actually means something completly unrelated to what I wanted to say, then what is the better way to express "Here are my ideas" in this context?
