After defeats against Uruguay and Ghana, England needed to beat Uzbekistan convincingly and still hope other results went their way.
But they only edged a 1-1 share of the spoils – thanks to Alex Nimely’s late leveler.
However, Eastick insists valuable lessons have still been learned.
"To play in a World Cup is a tremendous experience for any young footballer," he said
"I believe that all of the players who have been here will go back to their clubs as better players because of it.
"Since our preparations in Cyprus, their application has been good, they’ve conducted themselves very well and worked very, very hard.
"The players that were here have played to their maximum. I think we could’ve done better in creating more and I do think we lacked a bit of cutting edge."
Eastick also insisted he has ‘no complaints’ about England’s exit, following their previous performances.
"Ghana and Uruguay are without doubt the best two sides in this group and they’ve rightly progressed," he added.
"I asked the players for a better performance against Uzbekistan and that’s what we got."
